I use synthetic oil EXCEPT during break-in.
I use a cheap non-detergent 30W for cam break-in, change it to same and seat the rings, then use Valvoline Racing until first oil change, then switch to Synth. I doubt that one brand of synthetic is a whole lot better than another.
Synthetic will not... 1) Leave carbon deposites behind when exposed to extreme heat. 2) Will not turn into molasis in cold weather, quicker to circulate during cold startup. 3) Has been proven on the dyno to have less friction.

Rotella is popular in cases where the oil is changed after every race day, like in an Alcohol fueled application where the oil is contaminated quickly. Just not cost effective to use a high-dollar oil.


My current vehicles...
98 Explorer 5.0 AWD. 130,000 miles (run hard and used to tow frequently). Mobile1 5W30 when new, and recenetly upped viscosity to 10W40. 6,000 mile oil-change interval. No observed oil consumption between changes.

85 Mustang 5.0 warmed over 9.5:1 306. Mobil1 10w40.

I use Castrol. Not for any scientific reason, but because of John Force and because it's what my father has always run and it's never let him or myself down.

i believe the rotella is being used in new cam breakin due to the higher zinc content but i am not 100% sure. i wish someone would tell me what type of rotella to use for the breakin? 10w-30 or 15w-40 or 10w-40? rotella also makes a synthetic which is either 15w-40 or 5w-40?? any advice appreciated

"Rotella T" 15W-40 is used for break-in as said above for it's high content of Phosphorous and Zink to help any rubbing surfaces to mate better with LESS chance of abnormal wear. (Like flat tappet cam and lifters; or distributor gears; or wrist pins to pistons [or rod small ends]; or pushrod tips to rocker arms; or valve tips without roller rocker arms, etc.)
After that the application will usually determine which oil is best to be using for the situation. Every situation IS different.

Not the same content of phosphorous and zink in the 10W-30 as in the 15W-40 recomended for diesel engine use as well as gasoline engines.

oil

I've always used Havoline 20W-50 and had great results, no carbon built up, motor always looks like new on freshen-ups. In my jet boat I used Kendall 50W and also had good results. Chris

It seems that some people on here just like to ask pointed questions even though they probably know the answer already. Because, it apparently makes them feel like a bigger person to trap somebody in a mistake; when they could simply display the known answer themselves to begin with.
At this time it now appears that "Rotella T" 10W-30 and 15W-40 have the same amount of zinc and phosphorous; a year ago that wasn't true.

I use Schaeffer's oil. The stuff has been around since 1839, when they were making wagon wheel grease. They put they stats online. we run it in a blown alcohol deal and it holds up to the milking thing. check them out schaefferoil.com
